Unclear definitions of range_looks and azimuth_looks in abstracted metadata

There are two data fields in the abstracted metadata called range_looks and azimuth_looks. Both are of type float. The description column just says “number of range looks” and “number of azimuth looks”. Are these intended to be the number of actual looks (always an integer) or the effective number of looks (which would need to be a float)? The description column text could be improved to make this clear.
